They should have an mystery immunity idol with clues explaining what it possibly looks like, like in Indiana Jones and the Holy Grail. They must choose, but choose wisely. There would be fake ones hidden along with the real one. And no one would know it was the real one until they try to use it even the viewers.

Not a bad idea.
With the immunity gimmick they've got now, anyone that goes to Exile Island is given a new clue as to where the idol might be. Plus, once they get back to camp, they have to look for the idol without anyone seeing them.

I was thinking that they should make the idol be the machette or the pot that the tribe receives in the beginning of the game. You would have to use the clues to figure out what it is, but it wouldn't be hidden. Also, if you switch tribes, you could still have an equal shot at finding it.
